Project #3: W - Data warehousing

Project Description:

W Info Load, ETL team of the Bank, has to ensure mainly loading of data

from different domains, including Card, Customers, Deposits, ecommerce,

Marketing & Loans, as per Service Level Agreements (SLA).As per business

rules, extracted data is loaded to the W after transformation.

Any delay in data availability will have impact on bank's business. So

meeting SLA for all applications data is a challenge due to bigger size of

system & data volume and huge number of users accessing the system. To meet

SLA, quick resolution is required if any job fails in loading the data and

need to make enhancements and proper planning on the usage of system to

accommodate all users of datawarehouse. Also have to address if any data

issues occurs in the loading process.

Role: Lead Datastage Analyst
